Erica bought an assortment of t-shirts. 2/5 of the t-shirts were blue. 1/2 of the remaining t-shirts were red. There were 9 white t-shirts. How many t-shirts were there altogther?

#1**+4 **

ok.

2/5 were blue so that means 3/5 is left.

1/2 of 3/5 = 3/10 so 3/10 of them are red

which also means 3/10 of them were white.

if x was the # of t-shirts, then

\(\frac{3}{10}x=9\)

\(3x=90\)

\(x=30\)

we can check this by doing 2/5 * 30 = 12

3/10 * 30 = 9

and white = 9

\(12+9+9=30\)
